The trousers of the pantyhose worn at ordinary times are all designed differently. It may be that the crotch is widened, or there may be two seams on the buttocks to widen the crotch and buttocks, which is more comfortable. If you wear daily pantyhose to practice dancing, it won't look good, because the seams between crotch and buttocks will be exposed outside the dance jumpsuit. There is only one seam in the front and back of the dancing pantyhose, and the crotch is only slightly widened. The jumpsuit can completely wrap the seams inside, and the whole leg looks smooth and not cumbersome.
Dancing pantyhose must be worn with jumpsuits. Usually, if you don't wear a jumpsuit, it will slide down and be uncomfortable.
